Patented Mar. 24, 1942 GENAMENTING MACHINE Joseph G. Herbers,Cincinnati, Ohio, assignor to The Louis G. Freeman Company, Cincinnati,Ohio, a corporation of Ohio Application April 21, 1941, Serial No.389,641

20 Claims.

This invention relates to machines for use in the manufacture of bootsand shoes, and more particularly to machines adapted for marking andcutting operations upon skins, upper blanks, fitted or closed uppers,and the like, in which the work may be provided with markings at thesame time or as part of a cycle of operations during which the work mayalso be ornamented by per forating or cutting out a design, and whereinthe cutting and marking may be performed as a single factory operation.

The machine of this invention is also well adapted to the application ofmarkings with ink, pigment, or the like, as a cold operation; toembossing, and to marking with the use of heat, either With or Withoutcutting or perforating the work; it is also adapted to perform cuttingoperations to the exclusion of marking.

The invention features improvements upon devices and machines foreiiecting the mentioned operations as described and claimed in thecopending application of Benjamin W. Freeman, Serial No. 200,217, filedApril 5, 1938, patented May 13, 1941, No. 2,241,398.

Such machines are of a type intended for use as universal cutout andmarking machines, specifically intended for work on shoes, leather, andshoe materials, where the work is of widely varying contour and design,the machines being designed to operate, not only upon fiat material butalso to perform operations on other than fiat work, such as closed andfitted uppers, or other types of ring-like work.

In the general operation of these machines, after the work, the die, andthe pressure applying medium (usuallv a plunger arranged to applypressure fcrcing the work and die together, to effect the ornamentingoperation) have been aligned in the machine, the operator treadles themachine to effect the ornamenting operation. A conventional mode ofapplying power to the machine consists in the use of a constantly drivenpulley or fly wheel, and a clutch effective to connect the pulley to themain power shaft of the machine, upon such treadling.

It is important that the machine be brought to rest after a single cycleof operations, to avoid accidental, repetitious movement of theoperating parts, which might spoil the work or injure the operator, andto permit replacement of the work. To this end, it is customary to use asingle revolution clutch between the pulley and shaft, whereupon if theoperator neglects to remove her foot from the treadle, the machine willcome to rest after a single cycle, regardless.

In the embodiment disclosed as exemplary in the aforesaid Freeman PatentNo. 2,241,398, the die is arranged upon a carriage which is movablelaterally into and out of alignment with respect to a verticallyreciprocable work supporting plunger. The controls for the machine, asdescribed, are such that when the machine is treadled the die carriagemoves from an inoperative, rear, inner position to a forward location inthe machine, Where the die is aligned with the plunger. When thecarriage reaches this point, it trips a release for the main clutch andthe plunger actuating mechanism, and the plunger reciprocates intoengagement with the die, and returns. During this plunger movement, thedie and its carriage have momentarily remained stationary, and theplunger on its movement away from the die carriage, releases thecarriage actuating mechanism, whereupon the carriage returns to itsnormal inoperative position, leaving the Work support clear for theoperator to remove the finished work and place a new workpiece inposition.

By virtue of the single revolution clutch, the parts have all beenbrought to rest at the completion of this cycle ofaoperations, eventhough the operator should forget to remove her foot from the treadle,and hence the possible hazard of a repetition of the cycle While theoperator is endeavoring to change the Work, is eliminated, and thepossibility of accident reduced to an absolute minimum.

With some types of work, however, it may be desirable to bring the partsto rest prior to completion of the above described cycle. For example,if the machine is being used for embossing, or if the machine is markingwith the use of heat, it may be desirable to stop the relative movementsof the parts when the work and work support are engaged by the die, 1.e., in the herein illustrated embodiment, at a point in the cycle whenthe die carriage is in its outer position and the plunger has justcompleted the first half of its stroke. It is accordingly a primaryobject of the present invention to provide a means for creating thisdwell or cessation of action at the desired point in the cycle ofoperations.

An advantage of this dwell or delayed action comes into play when thereis a matter of embossing involved, or if a heated marking element formsa part of the die, whereby the heated edges of the marking die areeiiective to mark the work. The longer the contact between a heatedmarking edge and the work, the more pronounced Will be the heat markingand the same applies to embossing, whether pigment or other coloringmatter is used or not.

Again, various leathers and materials require different treatments,depending upon their character, and by means of an operator controlleddwell period, a satisfactory heat mark or embossed design can beapplied.

It has been customary in the art for some time to provide in thesemachines, a control for the die carriage, by means of which the die maybe stopped at its forward 01' operating position in the machine, toremain there until the machine is again treadled and the die carriagereturned to its inner or inoperative location. Under these conditionsheretofore, the plunger will have com pleted its cycle of operations andwill not be in engagement with the die. Such an arrangement is disclosedin the above referred to Freeman Patent No. 2,241,398, wherein means areprovided for bringing the die carriage to rest at either end of itslateral stroke, but no provision is made for simultaneously interruptingthe plunger movement and, accordingly, it is another important object ofthe invention to effect this dwell by bringing the parts to restsimultaneously and automatically in the desired relative positions.

To this end, an additional clutch control is provided whereby theclutch, instead of declutching the main shaft from its source of poweronly at the end of a complete cycle of operations, de-

clutches the shaft at the desired time in the cycle, thus necessitatinga retreadling of the machine to complete the cycle. But in neither eventwill the cycle or portion of the cycle overrun, because of anycarelessness on the part of the operator.

Under the present invention then, it is contemplated that a cycle ofoperations of the die carriage and plunger will be delayed orinterrupted such that the die carriage will come to rest in itsoperating location, and the plunger will come to rest at the same time,with the work under pressure and engaged with the die to receive theadequate period of treatment necessary, the machine thereafter beingtreadled to return all parts to their normal position.

While in the described embodiment of the invention, both in theaforesaid Freeman patent and herein, the die carriage is disclosed asoperable by power from the back of the machine to the front and return,the work support is illustrated as a plunger reciprocable toward andfrom the die carriage, and the die is mounted to operate upon the workfrom above, this structure is purely illustrative as obviously the diecarriage might be moved by hand, or the die might be mounted toreciprocate toward and from a workpiece on a non-movable support, or thedie readily might be arranged to cut upwardly, entering the work frombeneath. Machines embodying these variations in structure are all wellknown and conventional, in fact form the subject matter of many patents.

Since machines already on the market of the various types heretoforediscussed, well may be adapted to handle work which requires a dwell ordelayed action during the cycle of operations, it becomes a furtherobject of the invention to provide a means or mechanism for creating thedelayed action which may readily be applied to existing machines, with aminimum of alteration and expense. The improved mechanism of thisinvention is so arranged that it may be applied with hardly a change,removal or replacement of existing machine elements.

A single control, as a treadle or its equivalent, is preferably utilizedfor the mechanism by means of which the die may be moved into anoperating position, the marking elements of the die inked and/or heated,the main clutch of the machine released, the work support and plungersent through relative movements to effect an operation on the work, andreturn, and the die thereafter moved to a position out of the way of theoperator, who may then remove the work from the machine.

Ornamenting machines for forming cutouts in a workpiece or for markingsame, or for effecting both operations are, of course, known, but thepresent invention is designed to meet increasing demands of work, agrowth in the types of work to be produced, and operating pressures,without increasing the size of the machine itself, to an impracticaldegree. For example, when marking with heat, the nature of the markingmay be influenced by the degree of pressure applied to the work, i. e.,a hard, sharp blow as contrasted with a gentle continued pressure, butmore important than this is the time element during which the die andthe work are engaged, coupled with pressure. While desirably a dwellwill be provided at all times for a heat marking operation, it is animportant object of this invention to produce a dwell which may be underthe control of the operator, during the time that the work and die areengaged.

On the other hand, where cutting or perforating is an important part ofthe work, a hammer-like blow produces a clearer, sharper cutout than asqueeze between the cutters and the work.

Although the present invention relates specifically to improvements inthe controls and timing of operating parts of the structure describedand claimed in the co-pending Freeman Patent No. 2,241,398, the generalaims and objects as set forth therein are, however, retained herein.

To the attainment of the foregoing and other objects which will appearas the description proceeds, reference may be made to the accompanyingdrawings, in which:

Fig. l is a side elevation of a machine embodying the invention.

Fig. 2 is an enlarged side elevation of the upper half of the machine.

Fig. 3 is an enlarged front elevation illustrating details of thedelayed action controls and tripping mechanism.

Fig. 4 is an enlarged face view thereof.

Fig. 5 is an enlarged front elevation of the complete clutch controlmechanism.

Fig. 6 is an enlarged front elevation of the rear clutch wedge with itsmounting, and

Fig. 7 is an enlarged face view of the rear clutch wedge and mounting.

In the machine embodiment to which the present invention is applied, thedie illustrated is mounted for movement backward and forward within themachine, from an operative to an in operative position, and the plungeris illustrated as movable upwardly to the die when the die is in itsforward position, and downwardly therefrom. The clutch control mechanismfor producing a delayed action is shown as an additional control for theregular clutch and clutch control mechanism of the single revolutiontype designed to effect the movements of the die carriage and plunger,and with this additional control the clutch will be operated to declutchthe source of power from the main shaft, thereby to produce theinterruption or delayed action, enabling the machine parts to come torest intermediate the beginning and end of a normal Complete cycle.

The invention is by no means limited to the illustrative mechanism orclutch control. As shown, the control mechanism is separated into twoparts, positioned in two locations, and one of which parts is arrangedto control movement of the die carriage forwardly or outwardly, and theplunger upwardly, while the other is effective, upon a retreadling ofthe machine, to return the carriage and plunger to their startingpositions. Obviously, some equivalent mechanism positioned in a commonlocation might be utilized, or for that matter, a purely manual controlmight be utilized within the scope of this invention to accomplish thedesired results.

The important point is that for some types of work, and some degrees ofpressure, to which the machine may be adjusted, or which might becreated by the variation in the thickness, texture or character of thework, a longer dwell or period of engagement between the die and thework is required than with other types of work or conditions, and theinvention herein contemplates a means to this end.

Referring now to the drawings, wherein like reference numerals designatelike parts, there is disclosed a main frame or housing I 0, which may bemounted on a suitable base or bed B, and in which frame is mounted thecustomary drive shaft H, driven by a constantly rotating pulley P (Fig.1), from any convenient source, exemplified herein as the motor M. Thepulley is clutched to the shaft l I when the machine is treadled, by theclutching mechanism diagrammatically illustrated at 12. A toggle driveH! extends from the drive shaft H to the plunger I4, the controls forthis mechanism being synchronized with the actuating mechanism A (Fig.l) for the die carriage I5. A die l6 which may be of the combined cutoutand marking type, or solely for marking, or exclusively for cutting, issecured to and carried by the die carriage l5.

A treadle link I! extends from a treadle T (Fig. 1) to the treadle lever[8, to which it is connected while a spring S extending from the frameof the machine to the treadle link I? serves to return the treadle toits original position, after depression by an operator.

The treadle lever l3 operates through the trip ping lever hook It? torock the tripping lever 20, and the tripping lever 2i in turn actuatesthe link 2! (shown broken in Figs. 1 and 2). When the link 2! is pulledby the tripping lever 20, it rocks the crank 22, which is mounted forfree rotary movement about the shaft 23, and in so doing, a finger 24engages a pin 25 carried by an actuating arm or link 26 extending alongthe frame of the machine, to pull same forwardly. The link 26 isconnected to a circuit maker and breaker in an electro-magnetic clutchdrive (not shown) of the actuating mechanism A for the carriage 15, thusinitiating the first or forward movement of the die carriage.

In its forward movement the die carriage, through a tripping mechanism(not shown) partially rotates the shaft 23 to actuate an arm 21 which iskeyed to the shaft 23 adjacent to the freely rotatable crank 22, therebyshifting the rod 28, this rod being connected to the arm 2'1, and to theclutch control mechanism for the plunger drive. This clutch controlmechanism for the plunger drive comprises an arm 29 pivotally connectedto the rod 28, and also pivotally connected to a tripping lever hook 30,and the hook 30 acts to draw the tapered clutch wedge 3| out of the pathof a spring pressed, sliding clutch key 32, whereupon the clutchmechanism [2 will function to connect the pulley P to the shaft II, andthus actuate the plunger l4, through the toggle drive l3.

After the tripping hook 30 has slipped 01f of the wedge 3|, enabling thewedge to return to its position in the path of the clutch key, theclutch key upon completion of one revolution of the shaft II and pulleyP will be forced by the wedge out of clutching engagement, enabling theshaft H to come to rest. But in the meantime, the die carriage will havemoved forwardly and backwardly, and the plunger will have completed itsfull stroke up and down, and come to rest, thus completing a singlecycle of movements performed during the single revolution of the shaftII.

The actuating mechanism A, which includes an electro-magnetic-clutchmeans and other mechanism (not shown), and the clutch mechanism for theshaft ll together with the control means thus far described, includingportions not shown, are illustrated, described and claimed in theFreeman Patent No. 2,241,398, to which reference may be made for adetailed description thereof, this mechanism forming no specific part ofthe present invention. This mechanism will be utilized by the machine inits normal operation to produce a single complete cycle of operations,however, and is discussed herein for the sake of completeness ofstructure.

The operations thus far described will have the result of effecting ahammer-like blow upon the work, with no dwell between the work and die,this being a normal cutting operation, and/or marking operation wheremore printing or indenting is desired.

However, as stated above, some characters of work and some types ofoperation to be performed on the work require an interruption or delayin the cycle, i. e., a suspension of action in the movements of theparts, creating a dwell prior to completion of the single revolution ofthe main shaft I 8.

To this end, in order that an automatic interruption will occur, to befollowed by a restoration of the operation of the parts, the trippinglever 20 is formed With an upwardly extending hook portion 33 providinga notch 34. A control rod or bar 35 is mounted to extend along the sideof the frame It, and this bar is provided with a manipulating handle 3?,by means of which the bar may be shifted into various positions ofadjustment. A pin 36 is carried adjacent the forward end of the bar forpositioning in the notch 34, and the opposite end of the rod 35 ispivotally connected to a clutch lever 38, as indicated at 4|. When thepin 35 is positioned in the notch 36, a forward rocking movement of thetreadle lever 58 will rock tripping lever 20, which in turn will pullthe bar 35 to rock the clutch lever 38, the latter lever being pivotedto a stud 40 to permit this movement. Rigidly secured to the clutchlever 38 is a tapered clutch wedge 39 similar to the wedge 3!, and itfollows that the wedge 39 will be moved into and out of the path of theclutch key 32, in accordance with rearward and forward movements of therod 35.

Normally, the wedge 39 will be positioned in the path of the clutch key32, just as in the case of the wedge 31. The initial treadling of themachine will cause a momentary lifting of both of the wedges 3| and 39out of the path of the key, the wedge 3| being moved through the actionof the carriage controlled bar 28, and the wedge 39 being moved throughthe action of the rod 35. However, as the tripping hooks l9 and 30 slipaway from the tripping lever 20, the wedge 3|, respectively, the wedgeswill drop back into the path of the key. The movement of the wedge 3|away from the path of the key 32, will have permitted the clutch to comeinto play, but before the shaft II and the clutch key 32 pass through180 degrees of revolution, both wedges will be back in the path oftravel of the key 32, whereupon it follows that the wedge 39 willdeclutch the key 32 and cause the die carriage and plunger to come torest approximately midway of their complete cycle, i. e., with the diecarriage l5 at rest in its forward position and the plunger |4 holdingthe work in engagement with the die Hi. This position will be maintaineduntil the machine is retreadled by the operator, at which time the rod35 being again actuated forwardly, will rock the wedge 39 out of thepath of the key 32 to restore the clutch action.

Before the key has completed its second 180 degrees of revolution, bothwedges will again have dropped into the path of travel of the key, andthis time the wedge 3| will function to declutch the pulley from theshaft II by wedging the key 32 from a clutching engagement, and themachine will come to rest at the end of what has now become a completesingle cycle of its operations, and a single complete revolution of thepulley P and shaft II.

To effect a return of the tapered wedges 3| and 39 after they have beenreleased by the respective release hooks l9 and 30, suitable springs maybe provided, as indicated at 3|a and 3911..

It may be desired to operate this machine without a delayed orinterrupted action, and to accomplish this, obviously it is necessary tobreak the operative connection between the rod 35 with its adjacentparts including the tapered wedge 39, from the clutch l2. Advantage istaken of the pivotal connection 4|, and a grooved stud 42 rigidlymounted in the frame ID to accomplish this. The stud 42 is illustratedas having three grooves 43, although but one groove is necessary foroperating purposes. The additional grooves are provided for purposes offacilitating adjustment and assemblage of the stud in the machine, sinceif a plurality of grooves are provided extreme accuracy in the threadingand machining of the stud are unnecessary, and any one of the grooveswhich happens to reach a proper position will serve to accomplish thefunction of a stop-rest, as hereinafter pointed out.

When an operator manipulates the rod 35 by means of the handle 31 toremove the pin 36 from the notch 34, and places the pin 36 in the notch43 of the stud 42, this will pivot the wedge 39 about the pivot 40 to anopen position out of the path of travel of the clutch key 32. It will beobserved that the notch 43 is advanced from the normal position of restof the notch 34, or in a location substantially in the plane of thenotch 34 when the lever |8 has been treadled forwardly.

With the parts in the position just described, a single treadling of themachine will cause a complete single cycle operation of the machine inthe manner described above and in the Freeman patent, No. 2,241,398.

There may be some tendency in the rod 35,

due to its length, to partake of a distorted or sidewise movement fromits natural vertical path between the notches 34 and 43. To avoid this,and to hold the rod in its path, a guide finger 44, of a length toextend beyond the stud 42, may be rigidly mounted on the tripping lever20.

Obviously, suitable adjusting means can be provided for all parts, forexample, the connection between the rod 35 and the lever 38 may beadjustable, as indicated at 45, thereby facilitating adjustment of thewedge 39, and an adjustable stop 46' may be provided for the trippinglever 20, in fact, any suitable adjustment may be made wherever founddesirable.

In order to prevent any possibility of treadling a machine while a dieis being changed, the usual locking mechanism, of a type like thatdisclosed in the Freeman patent, No. 2,241,398, may be provided. Such ameans is illustrated as the pivoted latch 41 mounted on the side of theframe, which latch comprises a pivoted plate swingable into a positionto block movement of the pin 25 which forms a part of the rod or bar 26.With the latch swung to its down position, it will be evident that thetreadle will be ineffective.

The die is locked, conventionally, to the die carriage by mechanismwhich forms no part of the present invention, but which is under controlof the handle 48, which when the die is in its proper position on thedie carriage, can be manipulated to lock the die in place. When it isdesired to release the die, after the latch 41 has been properlypositioned, the handle 48 may be actuated, and during its die releasingmovement will open the switch, diagrammatically illustrated at 49, tobreak the circuit to the carriage drive mechanism. In other words, thesame movement of the handle 48 which acts to release the die whichpreviously was locked in place on its carriage, at the same timeeffectively prevents operation of the die carriage, and other parts ofthe machine.

It is essential that the die carriage come to a stop in a predeterminedposition at the front of the machine, in alignment with the worksupport, and this may readily be accomplished under electrical control,in the manner described in the aforesaid Freeman application, or bymechanical means, for example, as described in the co-pendingapplication to Benjamin W. Freeman, Serial No. 329.200, filed April 11,1940.

It is believed that the operation of the invention and its applicationto existing machines will be obvious from the foregoing description,inasmuch as the operation has been described in connection with theseveral parts. Briefly, when the machine is to be used with work whichrequires no dwell, that is no holding of the work and die in engagement,the rod 35 will be positioned such that the pin 36 is in the rigid stud42, and this mechanism will be inoperative. A single treadling of themachine will then effect a complete single revolution of the shaft H,and the actuating mechanism for the die carriage l5.

When it is desired to produce a delayed action, then the rod 35 ismanipulated to locate the pin 36 in the notch 34 of the tripping lever20, whereupon a treadling of the machine will produce an approximatehalf cycle operation. Retreadling of the machine will complete thecycle.

Since the primary clutch controls and treadle actuated mechanisms, orequivalents thereof, will be found on machines already in use, it is avery simple matter to adapt those machines to the use of the presentinvention. The only part which has to be replaced is the tripping lever20, equipped with the hook portion 33 providing the notch 34, and theaddition of the bar 35 and connections therefrom to the clutch l2,including the additional wedge 39.

Use of this additional equipment, however, increases the versatility andefiiciency of the machine and extends its workable range to embrace agreater variety of work than would otherwise be possible.

It enables the machine to operate either with a quick hammer-like blow,or with a dwell of indefinite determination, subject to the operator,thus permitting operations on all characters of work, and to theproduction of markings, ranging from one requiring an imperceptiblepressure to others requiring heavy indentation, embossing, or actualburning when heat is used.
